Embodiment 1
[0035] A foreign scientific research institution has done two sets of triaxial compression tests of the modified Cambridge model. One group is the drainage consolidation test (referred to as D1), and the other group is the undrained consolidation test (referred to as U1). The axial principal stress was increased in both groups of samples until the soil samples suffered shear failure. The new calculation method of parameter inversion proposed in the present invention is used to carry out parameter inversion, and the parameters obtained from the inversion are substituted into the finite element program to simulate the triaxial compression test of two sets of modified Cambridge models. Figure 3 to Figure 6 shown, where image 3 For the comparison between the calculated results of the initial parameters of the drainage consolidation test and the experimental results, Figure 4 For the comparison between the calculated results of the initial parameters of the undrained consolida...
Embodiment 2
[0040] The proposed site of a deep soft soil iron foundation pit is located in the Yangtze River floodplain landform unit area. Affected by human activities, the thickness of the filling layer is relatively large, ranging from 1.9 to 4.4 m. Below the fill layer, with a depth of 50.5-59.0 m above, there are soft clay soil, soft clay soil and silt, silt and fine sand sedimentary layers deposited in the middle and late Holocene, and the sedimentary layer of silt and fine sand, below which is the early Holocene sediments Pebble-containing gravel silty clay (or pebbly-gravel silty sand). The buried depth of the underlying bedrock is 59.2-61.3m, and the lithology is Cretaceous (K) silty mudstone, argillaceous siltstone, gravel-bearing sandstone and glutenite. The site is rich in groundwater and the depth of soft soil is thick, which will have a very negative impact on the excavation of the subway foundation pit. In order to effectively predict the deformation of the foundation pit ...
